The singer opens up to 'Rolling Stone' on her rekindled relationship with Chris Brown.

RIhanna has gotten a lot of heat for reuniting with her ex, Chris Brown. But the singer says she doesn't care what anyone thinks. In the Feb. 14, 2013, issue of Rolling Stone (out Friday), Rihanna opens up.

On people being upset about her reunion with Brown: "When you add up the pieces from the outside, it's not the cutest puzzle in the world. You see us walking somewhere, driving somewhere, in the studio, in the club, and you think you know. But it's different now. We don't have those types of arguments anymore. We talk about (stuff). We value each other. We know exactly what we have now, and we don't want to lose that."

On the opinion that Brown still hasn't changed, based on his behavior: "I know it comes off like that. And it doesn't help. For a long time he was really angry, and he felt like he couldn't get away from it, no matter what he did. But there's so many reasons why I ever reconsidered having him in my life. He's not the monster everybody thinks. He's a good person. He has a fantastic heart. He's giving and loving. And he's fun to be around. That's what I love about him – he always makes me laugh. All I want to do is laugh, really – and I do that with him."
